How do I use assertions in C++?

In C++, you can use the assert macro from the <cassert> header to check assumptions in your code.

Can you give me an example of how to implement it?

Sure! Here's a simple example:

#include <cassert>

int main() {
    int x = 5;
    assert(x > 0); // This will pass
    assert(x < 0); // This will fail and terminate the program
    return 0;
}

What happens if an assertion fails?

If an assertion fails, the program will terminate and print an error message indicating the failed assertion.

Is it a good practice to use assertions in production code?

Assertions are generally used for debugging and should not be relied upon in production code. They can be disabled in release builds.
